Work is a scalar quantity, meaning there is no direction associated with it. However, work can be either positive or negative, depending if it is working against the system or with the system. The SI unit for work is the newton-meter or the joule (J). It is measured by the magnitude of the force times the displacement occured if these are both in the same direction. Work always requires a system of more than just one object.
The work W done on an object by a constant force F is gven by W= F∆x, where F is the magnitude of the force, ∆x is the magnitude of the displacement.
Work can be expressed by these equations: W=∫F•dr or W=F•d,
where work equals the integral of the force in relation to distance, or the force multiplied by the distance
